Hi,I'm using the .NET 2.0 based implementation of the Rijndael class for encrypting data with a 256 bit key and attempting to decrypt the encrypted data with the same KEY and IV using Poco::Crypto APIs (poco-1.4.3p1) both running on the Windows XP platform.

However, the decryption fails. Any specific things that I could be missing or ought to keep and eye on?Any configuration parameters to get the .NET 2.0 and Poco::Crypto modules in sync?

I'm no expert in this but even if i was one, there's not enough information to form a meaningful advice. I'd try to decrypt same data with another tool. That will cut your problem in half and you'll know on which side it is and whether this is the appropriate place to seek help.
